Embodiment Construction

[0015] Such as Figure 1-Figure 3 As shown, the loudspeaker with variable orientation includes a cylinder 1 with an opening at one end of the cylinder 1 , and several horns 5 are evenly distributed and hingedly arranged on the end surface of the opening of the cylinder 1 . A slide plate 3 is fixedly arranged in the middle of the cylinder body 1 , and the slide plate 3 is provided with banner-shaped limiting grooves 10 corresponding to the number of horns 5 . A guide plate 2 is provided for rotation at the inner bottom of the cylinder body 1 , and a slideway 9 is provided on the guide plate 2 .

[0016] The slideway 9 is spliced ​​by two interconnected grooves, one of which has a semi-elliptical structure and the distance between its midpoint and the center of the guide plate 2 is smaller than any end of the groove and the center of the guide plate 2 The other section of the groove is a semi-elliptical structure and the distance between its midpoint and the center of the guide...

Abstract

The invention relates to a loudspeaker, in particular to an orientation-variable loudspeaker and a use method thereof. According to the orientation-variable loudspeaker, a plurality of loudspeakers are evenly distributed and hinged to the opening end face of a barrel, a sliding plate is arranged in the middle of the interior of the barrel, a guide plate is rotationally arranged at the bottom of the interior of the barrel, the sliding plate is provided with banner-shaped limiting grooves, and the number of the banner-shaped limiting grooves corresponds to the number of the loudspeakers; the guide plate is provided with a slideway, pull rod hinge seats corresponding to the loudspeakers in number are slidably arranged on the slideway, one end of each pull rod is hinged to the corresponding pull rod hinge seat, and the pull rods penetrate through the limiting grooves and are hinged to the side walls of the loudspeakers. By rotating the direction of the guide plate, the corresponding loudspeaker can face the required direction, and the sound effect of transmitting sound to people in different directions is achieved.

Description

technical field [0001] The present invention relates to a loudspeaker, in particular to a variable orientation loudspeaker and its usage method. Background technique [0002] The loudspeaker is commonly known as the horn, an electrical device that converts electrical energy into sound, and transmits electrical energy of different sizes to the coil. The coil generates magnetism and interacts with the magnet, causing the diaphragm to vibrate. Because the magnitude of the electrical energy is different, the vibration of the diaphragm is caused. The frequency and amplitude are constantly changing, so that the effect of the diaphragm on the air is constantly changing, forming a rich sound. [0003] Currently, the loudspeakers are installed in a fixed manner, and the sound emitting part of the loudspeaker faces a specific direction. In the face of different scene conditions, it is necessary to adjust the orientation of the speaker. If no adjustment is made, the ideal sound effect...
